WINDOW CHANNEL OR THE LIKE Filed Oct. 12, 1936 I A I I I A Patented Jan.18, 1938 UNITED STATES PATENT OFFICE '1 Claims.

The present invention comprises certain improvements in means forsecuring plate glass or window glass in place, especially for thepurposes of erectingstore or show windows, and the like.

.The construction of the invention is adapted for properly assemblingand securing sections of glass in the building of show cases, however,and can be used in difierent places where it is necessary to join twosections or panes of glass together at juxtaposed edges thereof.

' The invention takes the form of a special bar construction forfacilitating the uniting or connecting of glass sections or sheets ofglass where these members extend from one another at an angle, as forinstance at the corner of a showwindow. In addition, the invention makesprovision-for special attaching means between sections of glass whichlie in the same plane or edge to edge.

Among the objects of the invention are to provide connecting bars of'thetype referred to, useful at corner portions of a Window where the glasssections practically meet, and also useful at intermediate sections ofglass lying in the same plane, whereby a very solid mounting of theglassmembers is obtained, and an excellently finished appearance for thecompleted show or other Window construction secured, with provisionssuch that the glass members may be assembled on the supporting barmembers employed therefor, and clamped to the latter with facility andwithout liability of breakage of said glass members.

The invention takes different forms, of which several preferredadaptations are illustrated in the accompanying drawing and describedhereinafter in detail as to both construction andadvantages.

In the accompanying drawing- Figure 1 is a horizontal sectional viewtaken through the corner portion of a show or like window andillustrating glass windows or sections assembled or connected by meansinvolving'one preferred form of the invention, and further illustratingone preferred form of connection for glass sections disposed in the sameplane, the latter being adapted to be mounted at intervals in the lengthof the corner connecting means and serving as spacing bars for thecorner bars.

Figure ,2 is a sectional View taken approximately on the line 22 ofFigure 1.

Figure 3 is a View similar to Figure 1, but-illustrating a slightmodification of the construction of the corner or angle bar.

Figure 4 is a sectional view taken approximately on the lined-4 ofFigure 2, more clearly bringing out the construction of the spacingattaching bar for glass sections or panes which lie in the same planewhen set up.

Figure 5 is a view similar to Figure 1, showing still anothermodification of the main glazing bar structure in which clamp means areprovided to clamp the glass sections in place securely seated againstthe main glazing bar, without theaid of screws or other similarfastenings.

' Figure 6 is a view similar'to Figure 4, embodying a modificationaccording to the same principles as illustrated in Figure 5. Figure 7 isa perspectiveview of the clam means illustrated in Figures 5 and 6.

Referring first to the construction of my in' vention asembodied inFigure 1, the designation A- denotes the main glazing bar, B theassociated clamping bar,,and C the attaching screw means intermediatesaid bars A and B. The main glazing bar'A is of angular formation andis'designed to be used primarily where the glass sections I and 2 havetheir edges juxtaposed at acorner of the window or at some portion ofthe window from which the glass sections l and? extend'from each otherat an angle. of a hollow sheet metal body including the outer angularwings 3 and! having the remote edge portions thereof folded inwardly asat 5 and thence extending parallel with the portions 3 and 4 as The barA is comprised shown at 6 to provide channel portions or seats imatelyright angles as shown at 1 to provide shoulders at the edges of theadjacent glass sections l and 2. Thereupon, these portions 1 areextended slightly to'bring them together, they being interlocked at suchportions by interfolded parts asillustrated at 8. Openings pass throughthe interfolded parts 8 that unite the edges of the sheet metal thatmake the bar A, and the screws C are threaded into said openings. Saidscrews C, as previously indicated, are utilized-to attach the clampingbar B to the main glazing bar A in the space circumscribed by theinterior angle between the parts ii of said bar A.

The clamping bar *3 is provided with clamping wing portions 9 that arespaced from and practically parallel with the members 6 of the glazingbar A, and the parts 9 and 6 provide a space or channel between whichare received adjacent edges of the glass sections and 2 that are thusheldfirmly in-place seated against and attached together by the parts Aand B in the manner set forth.

From the foregoing description it will be understood that the mainglazing bar A is preferably of one-piece construction and is composed ofsheet material folded longitudinally into generally L- shape intransverse cross section, providing wing portions extending atapproximately right angles to each other, forming seats for the edges ofthe glass sections which are to be secured together, the free margins ofthe sheet material being brought together at substantially the medialaxis of the bar and interlockingly folded around and about each other.The interlocking folded parts of the bar lie intermediate the wingportions and adjacent to the juxtaposed edges of the glass sections, andserve .to support a suitable clamping member or members so as toprovide, with the wing portions of the main bar, channels within whichthe glass sections are adapted to be received. According to the form ofclamping member B illustrated in Figure 1, the clamping member issecured in position on the main bar A by a suitable fastening means C,such as a screw, which extends through the clamping member C and intosuitable apertures formed in the interlocked folded portions of the mainbar A.

The modified construction illustrated in Figure 3 is substantially thesame as that illustrated in Figure 1, with the exception that the parts6 of the main bar A are slightly inclined and are not exactly parallelwith the outer faces of the wings 3 and 4. The other parts of the bar Aand the clamping member B which are similar to the parts illustrated inFigure 1, are designated by the same reference characters. The purposeof inclining the parts 6" of bar A is to permit the application of puttyor other weather sealing means to these parts which form the seats forthe glass sections,

' whereby to ensure that the edges of the glass will be sealed againstthe entrance of dust, moisture, air, and the like. The putty or othersealing medium is designated I0.

Passing now to the construction of the spacing bars which are adapted tosecure glass sections lying in substantially the same plane, andreferring particularly to Figures 2 and 4, the main glazing bar isgenerally designated A and this bar is also preferably formed in onepiece. The sheet metal body of which the bar is made is foldedlongitudinally to provide hollow wing portions 3 and 4 extending insubstantially opposite directions and being substantially coextensive.The outer margins of the body are folded 'l inwardly as at 5' and 6' toprovide seats for the glass sections 22, and the free margins of thesheet of material are brought together and interlockingly folded aroundand about each other as at 8 in a manner similar to the construction ofFigures 1 and 3 above described. The interlockingly folded portions 8'lie substantially at the medial axis of the main bar A and intermediatethe ends of the wing portions 3' and 4.

Coacting with the main bar A are one or more clamping members B havingwings 9' disposed substantially parallel with the parts 6 of the wings3' and 4' of the main body A. These clamping members are secured to theinterfolded portions 8 of the main bar A by suitable fastening means Csuch as screws, in the manner previously described, the interfoldedparts 8' being provided with suitable apertures therein, and the wings 9forming, with the wings 3 and 4', channels for receiving the juxtaposededges of the glass sections 2- 2. In the form of the inventionillustrated in Figure 5, the main glazing bar A is substantially thesame as illustrated in Figure 1 and is adapted to have associatedtherewith a clamping member D which is preferably of such constructionas to be capable of being releasably at tached to the main bar A withoutthe use of screws or other equivalent fastening means. The form of themember D may be best seen in Figure 7. As illustrated, the member D iscomposed of resilient sheet material having its marginal edges bentinwardly asat I I and normally disposed in spaced relation to each otherfor gripping. the interlocking folds 8 of the main bar A. In otherwords, the distance between the edges IIII of clamping member D isnormally somewhat less than the width of the interfolded portions 8 sothat when the member D is forced over the folded parts 8, the edges IIIIwill engage the parts 8 with a firm gripping action, due to the inherentresiliency of the material of the member D. In order to prevent theclamping member D from being disengaged from the interfolded portions 8too readily and to provide more or less interlocking engagement of theedges II-I I with the portions 8, the folded portions 8 are preferablyso arranged as to provide longitudinally extending grooves ordepressions I2-I2 at opposite sides thereof. Of course, by theapplication of suitable force to the clamping member D, the member D maybe snapped off or applied to the main glazing bar A, at will. When theclamping member D is mounted on the glazing bar A, the portions I 3| 3thereof lie in spaced relation to the wing portions 3 and 4 of the mainbar A, and form therewith channels for receiving the juxtaposed edges ofthe glass sections I and 2, and the clamping member D serves to firmlyclamp the glass sections on their respective seats of the main glazingbar A.

The construction of Figure 6 is generally similar to that of Figure 4,and illustrates the substitution of a clamping member D like that shownin'Figures 5 and 7, for the clamping member B of Figure 4. The functionand manner of applying and removing the clamping member D according tothe form illustrated in Figure 6 will be readily understood from theforegoing description and need not be repeated. The parts of the mainbar A and clamping bar D similar to those parts illustrated in Figures 4and Shave been designated by the same reference characters in' Figure 6.It will accordingly be understood that Figure 6 illustrates the mannerof clamping the juxtaposed edges of glass sections disposed in the sameplane, against the seats provided by the main bar A, without the use ofscrews or equivalent fastenings of the Figure 4 construction.

In mounting the glass sections in the glazing bars of the variousconstructions herein disclosed, suitable provision should be preferablymade to allow for expansion of the glass sections. To this end, theglass sections may be cut so as to leave a slight space between theextreme edge faces thereof and the main glazing bars A or A, theseclearance spaces being designated I4 in each of the views of thedrawing.

It will also be understood that in any of the various forms of mainglazing bars, the portion 6 or 6' may be inclined as in Figure 3 anddesigis not absolutely necessary to do this in every case.

While the specific details have been herein shown and described, theinvention is not confined thereto, as changes and alterations may bemade without departing from the spirit thereof, as defined by theappended claims.
